6b98b52acc Fix reporting of EC shard sizes from nodes to masters. (#7835)
SeaweedFS tracks EC shard sizes on topology data stuctures, but this information is never
relayed to master servers :( The end result is that commands reporting disk usage, such
as `volume.list` and `cluster.status`, yield incorrect figures when EC shards are present.

As an example for a simple 5-node test cluster, before...

35fd1e1c9a optimize memory usage for large number of volumes
1. unwrap the map to avoid extra map object creation
2. fix ec shard counting in UpdateEcShards
